Who runs the work

John Williams on technical setup + deliverability, Kristy Morgan on copy + lifecycle program design, Sandeep Muley on segmentation + measurement. Read the full team page.

Email is the highest-ROI channel almost every brand under-invests in. We don't sell more campaigns; we sell better lifecycle. Most email revenue uplift comes from getting the welcome series right and shipping a real win-back program — not from sending more newsletters.

Deliverability lockdown

Authentication records configured. Sender reputation warmup. List hygiene (suppress + sunset rules). BIMI for brand-recognized inbox display.

Frequently asked

What ESP do you recommend?
For DTC: Klaviyo. For B2B: HubSpot or ActiveCampaign. For high-volume marketing: SendGrid or Postmark for transactional + a marketing ESP layered on top. We work with what you have, but we'll recommend a switch if the platform is bottlenecking your program.
What's MailChannels?
Cloudflare's email-sending integration. Free for transactional + lead notifications from Cloudflare Workers. We use it on every Cloudflare-native build (Goodlife Insurance, Summit Tracker). Not a marketing ESP — for transactional + lightweight automation only.
Do you write the actual emails?
Yes. Voice + tone fingerprint locked first, then production. AI-assisted drafts with human edit. Subject-line testing where volume justifies. Plain-text test for B2B; designed for B2C unless deliverability is suffering.
Deliverability problems?
Yes, we fix those. SPF, DKIM, DMARC, BIMI. Sender reputation through warmup. List hygiene (suppress 90+ day non-openers, sunset 180+ day non-engagers). Most deliverability problems are fixable in 30-60 days with discipline.
Lifecycle vs broadcast?
Lifecycle is where the revenue is. Welcome series, abandoned-cart, post-purchase, win-back, replenishment, lapsed-customer — each one is a small revenue lever, but together they routinely add 25-40% to overall email revenue without sending more campaigns.
Minimum?
$5K/month for email-focused engagements. Often bundled into eCommerce or SaaS retainers where lifecycle is one chapter.
